Normal Cognitive Aging

Normal Cognitive Aging

2013 November ; 29(4): 737–752 | Caroline N. Harada, Marissa C. Natelson Love, Kristen Triebel
The paper discusses the normal cognitive changes that occur with aging, both in terms of neurocognitive and structural-functional alterations in the brain. It highlights the importance of understanding these changes for their impact on daily function and distinguishing them from disease states. The authors describe the decline in processing speed, attention, memory, language, visuospatial abilities, and executive functioning. They also explore the structural and functional brain changes associated with aging, such as grey and white matter volume decline, mentalizing capacity, neuronal size and synaptic density, and white matter integrity. The practical implications of these changes are discussed, including their effects on driving and certain professions with mandatory retirement. The paper concludes by discussing factors that may mitigate age-associated cognitive decline, such as lifestyle activities, cognitive reserve, and cognitive retraining.The paper discusses the normal cognitive changes that occur with aging, both in terms of neurocognitive and structural-functional alterations in the brain.
